“In this fast-paced new thriller, Blood Line, international enemies want a lovable family with a heroic past, dead, right now! Their teenage daughter knows nothing of her parents’ work as professional spies, but quickly finds herself fleeing the comfort and safety of her world on an explosive flight for survival, with new dangers at every turn. She begins to learn the truth about her parents and joins them in discovering which among their international enemies wants them dead.

Blood Line is compelling, with accelerating pace, surprising twists and a spectacular ending—readers will be eager for the sequel, coming soon!”

“Blood Line's psychology is exquisitely wrought, its action is elegantly played out against the backdrop of political and criminal forces, and its ultimate results are satisfyingly unpredictable. 

Add a surprise conclusion that skillfully ends the saga while leaving the door open for future developments and the end result is a thriller that proves haunting and unique, recommended for even the most seasoned thriller genre reader.” 

“This debut thriller finds an entire family on the run from those who would sell bleeding-edge technology to the highest bidder. Ron and Valerie feel like true partners and parents, and Leecy is a believable teen (“…my life is on that phone!”). Clever scenes also have Ron playing with his legend as a one-man Native American kill squad who only used a knife and a tomahawk. Valerie’s past as a Mossad assassin is more explicitly referenced; readers learn that she helped get Boris Yeltsin elected.

Davis sets a solid foundation for more adventures. Sharply written, starring characters readers will be happy to meet again."  

“Rich character back stories make this spy thriller an entertaining read.  Fans of spy novels and series will enjoy this energetic and entertaining story of a family of spies.” 

“Blood Line is a quiet little gem of genius. I love espionage novels and I have read a lot of them, but I can assure you that I have never read a novel where the world of espionage is so smoothly blended with ordinary American family life. The genius of John J. Davis is that both facets of Ron and Valerie's characters are believable; the spy and the parent. Just as importantly for the reader, this family is very, very likable.” 5 out of 5 Stars
